(...) Hello Geoffrey Thanks for the positive comments! In order to get a steering system that could have that many axis of freedom in that amount of space it was necessary to use the ball-and-socket pieces. There may have been another way, but not (...) (17 years ago, 12-Dec-07, to lugnet.technic)

Thanks -- making a hexagon out of equilateral triangles occurred to me after submitting my post, but I really had no idea what was going on with the funny angle, so this has been very educational. As always, this is one of the most helpful and (...) (17 years ago, 10-Dec-07, to lugnet.technic)

(...) Try approaching it in steps. Can you make an equilateral triangle out of Technic beams? Don't worry about making the angles rigid, just make a structure with three equal-length sides, connected near the corners (connected with something that (...) (17 years ago, 10-Dec-07, to lugnet.technic)
